I wanted to have much longer wires for the screen, because it is sometimes useful to be able to carry it around.
I purchased some 3 meters long RS232 cables as well as some 10 pin -> RS232 interface cables.
It works pretty well, except for one little (but quite important) detail: I don’t have access to the SD card files anymore. It detects that the card is inserted in the home screen, but whenever I want to print from SD, it says that there is no memory card.
I’ve checked the continuity of all the wires and everything seems to be fine. When I put the old wires back, it works again.
Any thought about how I could solve this issue?
